我这个方法比较笨 , 但是有效果 , 百度很多都是有问题的 ,基本都是获取地址的API的问题, 我用的是TP , 所以我是把方法放在common中的 , 然后首页调用, 第一个 , 获取访客IP , 这个不多说 , 基本都行 //获取访客ip function getip() { if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP") , "unknown")) { $ip = getenv("HTTP_CLIENT_IP"); } else if (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR") , "unknown")) { $ip = getenv("HTTP_X_FORWARDED_FOR"); } else if (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR") , "unknown")) { $ip = getenv("REMOTE_ADDR"); } else if (isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($

项目中的那些事---下载pdf文件

由 我与影子孤独终老i 提交于 2020-01-09 03:30:46
最近做了一个下载pdf文档的需求，本以为使用HTML5中<a>标签的属性download就能简单搞定，不料IE竟然不支持这一简单粗暴的H5新特性，而是直接在网页中打开， 于是各种搜索之后得出以下结论：IE中下载文档时，要想直接下载而不是在浏览器中打开，就要给下载的请求添加一些header属性： 1、Content-Disposition: attachment; filename=filename 2、Content-Type: application/octet-stream; 现在以我做的项目为例，总结一下在IE中下载pdf等类型文档的方法： 1、服务器端语言：PHP 2、前端语言：Jquery 因为要设置header，所以只能走服务器 第一步：前端创建一个下载文件的按钮 <button class="btn btn-small btn-warning" id="df">下载pdf文档</button> 这里面的class是bootstrap中的样式，用过bootstrap的人应该都很熟悉，这里不再赘述 第二步：给这个按钮添加点击事件，当点击该按钮时发起一个下载文档的请求给服务器 $("#df").click(function(){ $.ajax({ url:"downloadFile", type : 'POST', dataType : 'json', success :

问题 I have read all topics regarding strpos() issues but I cant find one that will fix mine. So here is the code. foreach($titles_array as $k=>$v) { if(strpos($subject,$v) !== false) { $i++; $asd[$titles['id']] = $i; } } The script works good and I get the results I'm looking for but this error comes up : Warning: strpos() [function.strpos]: Empty delimiter I read that it might be an empty string or value in array but I've checked them both and I didnt found any empty string/value.

Crop string after 2nd full stop

由 人盡茶涼 提交于 2020-01-05 07:52:52
问题 In PHP, I'd like to crop the following sentence: "Test 1. Test 2. Test 3." and transform this into 2 strings: "Test 1. Test 2." and "Test 3." How do I achieve this? Do I use strpos? Many thanks for any pointers. 回答1: Something like that? $str = 'Test 1. Test 2. Test 3.'; $strArray = explode('.', $str); $str1 = $strArray[0] . '. ' . $strArray[1] . '.'; $str2 = $strArray[2] . '.'; 回答2: function isIndex($i){ $i = (isset($i)) ? $i : false; return $i; } $str = explode("2.", "Test 1. Test 2. Test 3
